JOHN R. KENNETT, OF TROY, NEWV YORK.

CYLINDER PAPER-MACHINE.

SPECIFICATION forming part of Letters Patent No. 777,345, dated December13, 1904.

Application filed April 18, 1904;,

To all 2071/0111 it may concern:

Be it known that 1, JOHN R. KENNETT, a citizen of the United States,residing at Troy, county of Rensselaer, and State of New York, haveinvented certain new and useful Improvements in CylinderPaper-lllachines, of which the following is a specification.

The invention relates to such improvements; and it consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings and the referencecharacters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several figures.

Figure 1 of the drawings is a top plan view of the cylinder end of acylinder paper-making machine embodying my invention, the felt beingremoved. Fig. 2 is a vertical cross section of the same, taken on thebroken line 2 2 in Fig. 1. Fig. 3 is a vertical longitudinal section ofthe same, taken on the broken line 3 3 in Fig. 1 with the felt in place.

The object of the invention is to adapt a cylinder paper-machine tocause the felting or intertwining of the fibers in the paper formedthereby. This I am able to accomplish by imparting to the cylinder,couch-roll, and neighboring portion of the felt a to-andfro rockingmotion endwise of the cylinder and roll and transversely of the felt.

Referring to the drawings, 1 represents the vat, 2 the cylinder, 3 thecouch-roll, and f the felt, all substantially the same as in theordinary type of cylinder paper -maehine. The ends of the shaft 5, uponwhich the cylinder is fixed, fit loosely in and are movable endwisethrough apertures in the main side walls of the vat, through whichapertures they project into the space inclosed by the boxes 6 outsidethe main vat at opposite ends of the cylinder. The journals of saidcylinder-shaft are mounted in bearing-boxes 7, each swiveled upon theupper end of a vibratory arm 8, pivotally mounted at its lower end at 9upon the bottom of one of the boxes 6. Longitudinal movement of thejournals in their bearing-boxes is prevented by means Serial No.203,610. (No model.)

of the collars 10, [ixed upon the cylinder-shaft on opposite sides ofeach bearingbox. One of the vibratory arms 8 is connected by means of apitman 11 with a crank 12 on the shaft 13, located outside the vat andadapted to be driven by means of a belt 14:, engaging a pulley 15, fixedthereon. The pitman passes loosely through an aperture in the outer wallof the neighboring box 6. Operation of the power-shaft 13 thus causes avibratory or rocking movement to be imparted to the arm 8 with which thepitman is connected, which vibratory movement is transmitted by thecylinder-shaft to the other arm 8 at the opposite end of the cylinder.The cylinder being fixed upon its shaft partakes of said vibratory orrocking movement. Mounted upon the bearing-boxes 7 in fixed relationthereto, respectively, are posts or brackets 16, in the upper ends ofwhich are journaled the opposite ends of the couch-roll shaft 17, whichshaft is prevented. from endwise movement in its bearings by means ofthe collars 18, fixed upon the shaft on opposite sides of its bearings.The couch-roll is lixed upon its shaft, and the posts 16 form rigidconnections between the bearings for the cylinder and couchroll, so thatas the cylinder-Snpporting arms 8 are vibrated in the manner abovedescribed both the cylinder and couch-roll are caused to partake of suchvibratory movement without disturbing their relative positions. The feltbeing passed around the couch-roll, that portion of the felt which isadjacent to the couchroll will also partake of such movement withoutdisturbing the relative position thereof.

The bearing-boxes 20 for the couch-roll shaft may be mounted in verticalslideways 21 in the posts 16, res 'iectively, and each of saidbearing-boxes may be forced toward the cylinder to produce pressurebetween the couch-roll and cylinder by means of an overhanging lever 22,provided with a weight 23 and adapted to engage the upper side of saidbearing-box.

As the felt travels over the couch-roll and the couch-roll and eylind erare rotated in the operation of the machine the vibratory movementimparted in the manner above described causes a displacement of thefibers of paperstock on the surface of the cylinder and felttransversely of the general direction of movement of such fibers,causing the fibers to be interwoven or intertwined and felted togetherand resulting in a better and stronger product.

As a means for closing to the passage of the pulp from the vat betweenthe side walls of the vat and ends of the cylinder I provide a flexibleor bellows-diaphragm 25, extending from each side wall of the vat to theneighboring end of the cylinder. This diaphragm is permanently connectedwith the vat-wall, as by tacks or nails 26 inserted through one of itsedges, its other edge being held in close engagement with the end of thecylinder without interfering with the rotary movement of the cylinder.

This I am able to accomplish by mounting upon an end portion of thecylinder of reduced diameter a close-fitting hoop 30, which is, however,loose enough to permit the cylinder to turn therewithin, with which hoopthe other edge of the bellows-diaphragm is permanently connected, as byrivets 27. It is necessary only that the bellows-diaphragm extend abovethe level of the pulp in the vat.

The flexible or bellows diaphragms readily adapt themselves to theendwise-shaking movement of the cylinder and at all times form aconnection closed to the passage of pulp between the ends of thecylinder and side walls of the vat.

The side walls of the vat are provided with apertures 29 within theareas inclosed by the respective bellows-diaphragms, through whichapertures the water which passes to the interior of the cylinder canescape into the respective boxes 6, from which it can be re' moved inthe usual manner.

Any known means may be employed to cause the hoops 30 to move in unisonwith the cylinder in its vibratory or shaking movement. I have shown aseries of springs 31 interposed between each of said hoops and theneighboring side wall of the vat, which serve to always hold the hoopsagainst the end portions of the cylinder of larger diameter, saidsprings contracting as the cylinder moves toward the side wall withwhich they are connected and expanding when the cylinder moves in thereverse direction.

W'hat I claim as new, and desire to secure by Letters Patent, is

1. In a cylinder paper-machine, the combination with the cylinder; androckable bearing-supports for the cylinder; of means for rocking saidsupports.

2. In a cylinder paper-machine, the combination with the cylinder; of apair of vibratory arms adjacent to the opposite ends of the cylinder;cylinder-bearings swiveled in said vibratory arms respectively; andmeans for imparting to said arms vibrating movements.

3. In a cylinder paper-machine, the combination with the cylinder; andcouch-roll; of a pair of vibratory arms adjacent to the opposite ends ofthe cylinder; cylinder-bearings swiveled in said vibratoryarms-respectively; bearings for the couch-roll fixed respectively to thecylinder-bearing; and means for imparting to said arms vibratingmovements.

In a cylinder paper-machine, the combination with the Vat; the cylinder;and means for shaking the cylinder; of a hoop mounted upon an endportion of the cylinder of reduced diameter, said hoop being adapted topermit the rotation of the cylinder therewithin; springs interposedbetween said hoop and the neighboring side wall of the vat; and aflexible diaphragm connecting said hoop with said side wall of the vat.

In testimony whereof I have hereunto set my hand this lath day of April,190 i.

JOHN R. KENNETT.
